Launching in 2019, BMW's brand new X7 sets new standards of colossal bigness for the Bavarian brand, starting with a beaver face comprising the "largest kidney grille in BMW history." It also promises plenty of high-tech goodies, intelligent, adaptive luxury trim and an "agile and versatile" drive … for its size.

Let's get that size out of the way. The X7 is 5,151 mm (202.8 in) long, 2,000 mm (78.7 in) wide and 1,805 mm (71 in) tall, making it the biggest Beemer in the catalog. That allows it to run either six- or seven-seat layouts (depending on whether you want two or three seats in the middle) with "uncompromised space in the third row."

Back-row passengers shouldn't feel too short-changed, either, apart from the whole lack of a dedicated door issue – but they do get their own armrests, cup holders, electric seats and USB charging ports. And if nobody's back there, the back two rows can be folded forward to boost luggage space from 326 L up to an enormous 2,120 L that might have some vans looking sideways at you. The tailgate is a split clamshell design, so you can pretend you're rocking a Rolls-Royce Cullinan as you slide your muddy mountain bike in the back.

Up front, the new Live Cockpit Professional dash gives you two 12.3-inch screens, one as your main dash and one as a control screen. You've got the option to use touchscreen, the iDrive controller, gesture control and buttons on the steering wheel, but BMW is putting a lot of work into its "hey BMW" voice control system, to the point where you can ask it "how's my oil level," or tell it you're feeling a bit tired, in which case it'll adjust things like mood lighting, music and temperature to help you stay focused.

It doesn't stop there. A "caring car" function adjusts all these things, as well as the ambient light/shade levels, the aroma in the cabin, the heated and cooled seats and things like massage seat functions to suit your mood. This car is clearly trying its best to create a range of different atmospheres in a way even the smartest of smart homes would struggle to match.

Keyless entry goes to the next level by not even requiring you to carry a coded fob – you can enter and start the car as long as you've got your smartphone on you.

Speaking of phones, the X7 has a nice wide tray for them to live in, with a lid and wireless charging, situated right by the heated and cooled beverage holders and in front of a glass-topped gear selector that looks like it belongs on the end of a cane.

In terms of driver assist, the X7 doesn't offer any kind of hands-off autonomy, but short of that, you name it and it's there. Adaptive cruise with speed limit assist that goes all the way down to stop/start speeds, steering and lane control assist, evasion aid, and auto emergency braking are all in there, as are cross-traffic, priority and wrong-way warnings, a latest-gen head-up display and fully automated parking.

Moving to the meat of the car, the X7 will launch with a range of engine options, each paired with an 8-speed transmission and xDrive intelligent AWD. The muscle king of the motors is the xDrive50i gasoline V8, which makes 456 hp (340 kW), while the efficiency king is the six-cylinder diesel xDrive30d, which gets a very impressive 6.5 L/100km (43.5 mpg) considering the size of this thing. There are several other options, but nothing electric or hybrid as yet – although those are sure to follow.

Wheels are 20 inches as standard, with up to 22 inches available as options, and suspension includes air springs at both axles and electronic damping. Options abound throughout the car, and include an off-road package that enables separately tailored driving modes for sand, gravel, rocks and snow.

The overall impression is one of size, space and intelligent, high-tech luxury that strives to always be ready to provide the perfect environment. It's presumably focused on the American market, where the X7 should be well placed to take on Mercedes-Benz's equally massive and luxurious GLS.

The X7 will be produced at BMW's plant in Spartanburg, South Carolina, and will hit showrooms in March 2019.
